Totally new to homeschooling my 4 year ol

So I had my daughter enrolled in preschool.  She will be 4 in the beginning of november.  She misses our school cut off date my 1 month.  I had her enrolled in the 4 year old program because she has been writing her name, knows her numbers and letters etc.  On the 3rd day the teacher told me she wasn't "socially" ready for the 4 year old program.  ie she wsan't sharing like the other kids and she didn't take direction like the other kids.  To say the least I was a bit annoyed because they made up their mind about her after only 3 hours of class time.  They said academically she was great.  They claimed they had to watch her the entire time.  I was like well, thats your job.  The school also said she wouldn't do criss cross applesauce.  She told the teacher no. 

Anyway- she is in soccer once a week, takes piano lessons and goes to the libray once a week for story and craft time.  She also has plenty of friends that she sees, so I have decided to homeschool.  The school really doesn't know what they are missing.  They just didn't give my daughter a chance.

Since she is almost 4 and i have never done this before, where do I even begin.  I put a bunch of books on hold at the library. 

Ack it seems so overwhelming.  how many days a week, how long per day etc.  thanks for  the help
